PA66 Lub Raj rau High-Performance Thermal Break Strips

PA66 lub ntsiab lus, txhais rau daim ntawv pib ntawm polyamide 66 tsis muaj kev pab, tau siv ntau hauv qhov kev tsim kho tshwj xeeb vim li qhov zoo tshaj plaws ntawm kev ua haujlwm, kev cua sov, thiab cov khoom siv. Cov ntsiab lus no feem ntau muaj qhov chaw kis tshaj plaws, muaj zog siab, nyab, thiab tiv thaiv kev puav tseg thiab kev rub. Qhov tseem ceeb yog qhov zog tshaj plaws ntawm 80–90 MPa, kev rov qab ntawm 10–50%, thiab qhov sov tshaj plaws nyob rau 260°C, thiab qhov sov tshaj plaws nyob rau 90°C ntawm 1.82 MPa. Cov ntsiab lus no tau raug tsim los ntawm kev ntxig, kev tshuab, lossis kev ntxig nrog, muaj nuj nqaij sov recommended ntawm 270–290°C thiab nuj nqaij tshuab ntawm 80–100°C kom paub meej qhov kis tshaj plaws thiab kom tsawg qhov loj (feem ntau yog 1.0–1.5%). Vim PA66 muaj kev nyob ruaj khov rau dej, cov ntsiab lus yuav tsum siv nuj nqaij 80–100°C rau 2–4 teev kom tiv thaiv kev puav tseg hauv kev tsim kho, uas tuaj yeem ua rau kev hloov pauv thiab kev ua haujlwm. Cov kev siv yog ntau yam, suav nrog cov rooj sib thooj, cov rooj sib thooj, thiab cov rooj sib thooj hluav taws xob hauv kev lag luam tshwj xeeb, kev lag luam tshwj xeeb, thiab kev lag luam hauv kev lag luam tshwj xeeb, qhov chaw qhov chaw muaj kev tiv thaiv, kev tiv thaiv hluav taws xob zoo, thiab kev tiv thaiv rau cov hydrocarbons yog qhov zoo. Cov cuab yeej tshwj xeeb, zoo li kev nyob ruaj ruaj thiab UV sensitivity, tau raug xaiv los ntawm cov khoom siv zoo li cov khoom siv sov lossis cov khoom siv tiv thaiv. Cov khoom siv thiab kev nyab xeeb yog tshwj xeeb dua, PA66 cov ntsiab lus tuaj yeem siv dua tab sis yuav tsum muaj kev daws teeb meem kom zoo kom tshwmsim cov yam ntxwv. Nyob rau saum npoo, PA66 cov ntsiab lus muaj qhov tseem ceeb rau kev tsim kho, nyob rau qhov kev tsim kho thiab kev ua haujlwm nyob rau qhov sov tshaj plaws, thiab feem ntau tau raug tsim rau cov khoom siv lossis cov khoom siv kom raug rau cov kev siv tshwj xeeb nyob rau qhov chaw tshwj xeeb.
